Michael A. Taylor's defensive fWAR (2.7) is the best in baseball.
(Image removed from quote.)
Doubt he could have done this here though. He seems like the kind of guy that needs his team's confidence.
I think that is defensive runs saved, not fWAR. His total WAR (sounds like a TV series on WWII) is 0.6, based on 5.7 runs above average - 2.7 from D, 1.9 from playing every day, and 1.0 from his offense. But yes, that's the best of any non-catcher.
Trea, by the way, is 2.0, 4th among SS.
